The study tracks every vehicle that drives through the area in a two hour period, said TxDOT Beaumont district spokeswoman Sarah Dupre. The determination comes after studying the slowest and the fastest drivers to determine what speeds people are most comfortable with.

These studies are commonplace and anyone can request it, she said, but no other locations are currently under consideration for speed limit readjustments.

The study for the FM 943 was requested by a citizen, Dupre said. Cities often request them.
